ROBERT SIMON, OF UNION HILL, NEXV JERSEY.

. LOOM.

SPECIFICATION forming part of Letters Patent No. 453,280, dated June 2, 1891.

Application filed June 25,1890.

To all whom it may concern.-

' Be it known that I, ROBERT SIMON, a resident of Union Hill, Hudson county, State-of New Jersey, have invented an Improvement in Looms, of which the following is a specification, .reference being had to the accompanying drawings, forming part hereof, where- 1n Figure. 1 represents a front view of part of a loom having my improvements applied thereto. Fig. 2 is a horizontal section on the line 0 c, Fig. 1, showing the shuttle-race and the brakes for the shuttles. Fig. 3 is a similar section without the brakes, they having been removed. Fig. 4 is a horizontal section on the line 70 7c, Fig. 1. Fig. 5 is an enlarged face view of one end of the shuttle-race, part being broken away to display the end brake. Fig. 0 is a plan View, partly 'in section, of that which is represented in Fig. 5. Fig. 7 is a cross-section on the line 0 c, Fig. 6. Fig. 8 is a detail top view of the center brake; and Fig. 9, a cross-section on the line 0 c", Fig. 8.

This invention relates to a new mechanism for utilizing on the same loom two or more loose shuttles for weaving two or more independent fabrics; and the invention consists, mainly, in combining with the, ordinary end pickers one or more intermediate picker and suitable stops and actuating-rods for moving simultaneously by theaction of any one end picker the entire series of shuttles in one direction and thereafter moving by the opposite end picker all the shuttles in the opposite direction.

The invention also consistsin other details of improvement'that will be hereinafter more fully specified.

In the accompanying drawings, the letters A and B represent the ordinary beams upon, which the finished fabrics are wound.

D is the batten, and D E the harness.

E E are the reeds, and G G the shuttles, the illustration showing in Fig. 1 two shuttles for weaving two independent fabrics on the same loom.

F F are the end brakes for arresting "the shuttles at the ends, and F is the middle brake for arresting the shuttles between the fabrics.

L L are the end pickers, and L is the central picker.

II is the shuttle-race. lVithin this shuttlerace is a groove or, preferably T-shaped, for receiving thepickers L L and L and for also receiving the intermediate rods 1) p, which are loosely placed in said groove 11, and are arran ged,respectively, between the said pickers, there being one such rod between every two pickers. Figs. 4, 7, and 9 show the rods p between these pickers, and it will appear from an inspection of Fig. 4: that when the picker L on the right-hand side is moved to the left it will, by the rodp adjoiningit, move the intermediate picker L, and this by the next succeeding rod 1) will in turn move the other end picker L to the left, and that in turn when afterward the left-hand end picker L is moved to the right, the intervening rods 19 will cause the remaining pickers to be moved to the right also. Consequently as the shuttles G G are shown in Fig. 3, each on the right-hand end of its course, it follows that by pushing the right-hand picker t0 the left both shuttles will be moved to the left, and that thereafter when the opposite or lefthand end picker is moved to the right both shuttles will be moved to the right, and this arrangement may be multiplied ad libitum, so that more than two shuttles may thus be given motion for throwing each its own weftthread into its own warp.

Suitable stops 0 (shown in Fig. 4) are rigidly secured on the shuttle-race for arresting the movement of each picker. Of course each shuttle must at the end of its throw be received in an appropriate brake, and I have provided for this purpose the end brakes F F, whose construction is more clearly represented in Figs. 5, 6, and 7, and an intermediate brake F, Whose construction is more clearly represented in Figs. 8 and 9. Each end brake F contains, besides the nsual stationary overhanging rod at, having flange 6, two pivoted and spring pressed bladesnamely, a longer blade f and a shorter blade j. Both these blades are by preference pivoted to the shuttle-race by the pin r, and each is slotted near the opposite end, the longer blade at h and the shorter blade at h. A pin 11 passes through the slot 7?, and a pin 1" through the slot h. The blade f may have an overhanging ledge g to extend over the shuttle, and, as is usual in such cases, its acting or breaking edge is sloping into the path of the approaching shuttle, said slope being clearly indicated by the dotted line beneath the letter g in Fig. 6. The blade j is shorter than the blade f, and extends into the path of the shuttle with a sloping edge, as is shown by the letter Z in Fig. (3. The blade f is in 0011- tactwith a spring on hearing against its outer side, and in like manner the blade j is in contact with a spring on, so that each of these blades is spring-pressed to the extent of the slot therein into the path of the shuttle. \Vhen now the shuttle advances from the position shown in Fig. 6 toward the brake, it first encounters the sloping edge-of the springpressed blade ft and after that the sloping edge of the spring-pressed bladej, and is thus gradually but surely arrested at the proper place for receiving the next stroke of the end picker. The central brake F can have but a single movable blade inserted in a slot of the shuttle-box back, and which is shown at t in Fig. 8. This single blade 25 has an undulating contact-edge u for the shuttle to contact with, no matter from which side the shuttle approaches this brake, and springs 11 c bear against the outer side of this blade 15. Vhen the shuttle approaches this intermediate brake F, it first encounters one of the projecting undulations, and is thereby slackened in its speed, and then encounters the second undulation, which finally arrests its motion.

The operation of this mechanism is briefly as follows: hen one of the end pickers Lis moved by its picker-stick, it throws the shuttle next to it through its appropriate warp; but the picker doing this also throws by its rod 1) the intermediate picker L, which in like manner throws the second shuttle through its warp, and so on with as many shuttles and intermediate pickers as the loom may carry. The first shuttle is received in the intermediate brake F, which limits its stroke. The last shuttle is received in the end brake F. After this the movement of the opposite end picker throws all the shuttles in the op posite directions in the manner already described, and thus I have a series of shuttles arranged on the same shuttle-race, each one being independent of the other shuttles,

and yet each moved by the same main picker. I am thus enabled by this mechanism to weave a series of ribbons or other fabrics on-thc same loom simultaneously by the speedy action of shuttles that are thrown in contradistinction to the slow action obtained by shuttles or pickers that are connected together by chains, racks, belts, or the like in positive manner.

Having now described my invention, what I claim isv 1. In a loom, the combination of the end pickers L L with one or more intermediate pickers L, the grooved shuttle-race II, and the disconnected rods 19 p, placed in the groove of the shuttle-race between the pickers, all arranged to communicate motion by either end picker to the disconnected rod between it and the next intermediate picker, substantially as herein shown and described.

2. In a loom, the combination of the end pickers L L with one or more intermediate pickers L, the grooved shuttle-race II, the intervening disconnected rods 19 p. and with two or more shuttles G G, said shuttles being arranged to be thrown by said pickers, substantially as herein shown and described.

3. The end brake F of a loom, composed of the spring m, the bladef, in contact therewith and having sloping contact-edge for the shuttle, and the independent bladej, having another and distinct sloping contact-edge for the shuttle, and the spring m, substantially as herein shown and described.

4. In a loom, the intermediate brake F, the same consisting of loose plate 25, having undulating edge u, and of the springs 11 1), both bearing against said plate, substantially as herein shown and described.

5. In a loom, the combination of the end pickers L L, one or more intermediate pickers'L, intervening rods 19, shuttles G G, end brakes F F, having spring-pressed blades f and j, and one or more intermediate brakes F, each having a doubly spring-pressed blade t with undulating edge,substantially as herein shown and described.
